I don't understand the need for this limitation.
Yes, if you compress and encrypt a backup over several volumes, I accept that you can only read the full directory and recover your stuff if you can have space to read it all back to your drive. You have to lose something, after all.
So, given the above limitation, why does toast refuse to span DVDs if you click on the compress or encrypt option? Couldnt it just warn you that you have to restore the whole bang shoot or nothing?
This might well be an enhancement request, but, please, I'd love to be able to have an encrypted and compressed backup that required me to restore everythign before it worked, but spanned several volumes.
Is there another backup tool that does this?
